STONE

Natural Stones are quarried out of mountains or underground from all over the world and

then cut into blocks.

One beautiful characteristic of natural stone is that there are no two pieces of natural

stone alike. Some stones may have extreme variation in color and veining from tile to tile

or slab to slab.

This characteristic is common in many types of stone, and is part of the inherent beauty of

using a natural product in your home.

Stone is a heterogeneous substance characterized by a wide range of:

.Mineral compositionsTextures

Rock structures.

DurabilityStrength

Both Strength durability are affected by texture and physical characteristics

PorosityWater absorption

Coefficient of thermal expansionFire resistance.

massive appearance to structure.

3.Paving stones.

Sandstone is a popular stone with sculptors.4 .5.Good and durable construction material

.6.Thresholds and steps in manor houses7.War memorials in the 19th and 20th centuries.

8.Limestone for burning lime and also for manufacture of cement.

About Natural StoneFor centuries, stone has been used by

nearly all civilizations. Each corner of the world and each layer of earth yields a

Stone may be classified according to geological into the

Following types:

Igneous rock such as granite and malachite is formed by

The crystallization of molten magma.

Metamorphic rock such as marble and slate has undergone a change in structure texture or composition due to natural agencies such as heat and pressure especially when the rock becomes harder and more crystalline.

Sedimentary rock such as limestone sandstone and shale is formed by the deposition of sediment by glacial

Action.

As a loadbearing wall material stone is similar to modular unit masonry. Although stone masonry is not necessarily uniform in size it is laid up with mortar and used in compression. Almost all stone is adversely affected by sudden changes in temperature and should not be used where a high degree of fire resistance is required.
